Not really, but I would consider trying downloading the Mesa source and compiling it myself. Since the error is happening somewhere in the OpenGL libraries (and is not really being replicated on other user's platforms), the only cause I can come up with is a problem with the libraries (and mismatched libraries is the most common problem). Compiling Mesa is actually pretty easy, so it is worth taking the effort to check.

No, we didn't compile OSMesa ourselves, but we installed OSMesa library on each node downloading the .deb packages with: apt-get install libosmesa6 apt-get install libosmesa6-dev Have you got any other idea? Thank you again. Luis 2009/10/20 Moreland, Kenneth <[email protected]> Could it be a problem with mismatched libraries? I notice in the error below that it occurs in /usr/lib/libGL.so.1. This is a system library. Did you compile OSMesa yourself? If so, then you should not be using the system GL libraries; you should be using the libraries that you compiled when you also generated the OSMesa library. -Ken On 10/20/09 1:56 AM, "myaccountmail9 myaccountmail9" <[email protected] <http://[email protected]> > wrote: Hi, we have a Linux (Debian) cluster without gpu and we have a big problem using Paraview 3.6.1in client - server mode.
